Traditional Leaded Lights


How are leaded lights, stained glass and traditional windows made today?

In order to understand how things are made today it is a good idea to be familiar with the terminology that was used historically and much if which is still used today in our Glossary of windows.

In this area of the website we are going to build and explore the different methods for making traditional windows today and some of the restoration process. Any work that involves period property restoration generally requires patience, dedication and normally a passion for preserving the heritage of often extremely old and significant architectural features. So in that sense there is a tremendous sense of pride that we and others take in the process, in the knowledge that the results will usually be stunning and remain as a legacy beyond our lifetimes.

Making traditional leaded light is an art and methods have not changed a great deal for many decades. We have created a page dedicated to the process, explaining each stage along with pictures in the hope we can inspire and help people who are interested. Just click on the picture opposite to see more or here - leaded light construction.

We have tried to explain how to make lead panels using words and pictures but it cannot replace the real thing of course. Whilst we do not run training courses we do have a thriving and busy workshop making leadlights in Thame, Oxfordshire. You are more than welcome to drop by and see work in progress or maybe discuss your own project - see contact page.

Stained Glass construction & process

Initially stained glass panels were formed and created by using coloured glass separated by lead came. The term “stained glass” is generically associated with churches and ancient buildings stemming from mediaeval times. Although methods and types of glass and glass production have changed in modern times, the techniques employed by stained glass professionals date back to the middle ages.


The processes involved in stained glass creation and some insight into the techniques and materials required which make this a fascinating subject are described really well in various websites online. A good example of this is: How stained glass is made.
